The 26-year-old Northern Ireland international made 11 appearances for The Millers last season and has recently recovered from a collarbone injury but found first-team opportunities limited due to the form of Ben Mee.

Dummigan, 19, has been an integral part of the U21 Development Squad this season and will now look to gain experience at Boundary Park.

The Northern Ireland youth international joins on a one-month youth loan.

Young Burnley goalkeeper Danijel Nizic 20, has been a regular for the Clarets Development Squad in the last two seasons.

Nizic has already enjoyed two loan spells away from Turf Moor last season, at Vanarama Conference North side Chorley and Conference North side Workington.

And the former Sydney FC goalkeeper will now link up with the league One Railwaymen for a month.
